[0038] When the rotating roller 206 and the extending shaft 207 slide outward along the lower seat 104, the short rotating rod 315 will be driven to rotate, thereby driving the connecting frame 301 to descend, and the lower spring 314 will be compressed, so as to adjust the position of the inner grinding head 303 according to the position of the composite paper tube 117.

Under the action of the inner convex ball 306, the two-way screw rod 302 and the inner grinding head 303 spirally move forward to grind the inner wall of the composite paper tube 117. Then the switching motor 106 rotates to drive the tube inlet frame 101 to slide and the grinding cover 109 to rotate. Before the tube inlet frame 101 reaches the top of the lower seat 104, the ground composite paper tube 117 is taken out.

[0039] The working principle of the composite paper tube internal and external grinding device disclosed in the present invention is as follows: a composite paper tube 117 is placed into the tube inlet rack 101 from the tube inlet 102, the composite paper tube 117 falls onto the blocking block 115 and is blocked by the blocking block 115, then the lower pressure electric cylinder 103 is extended to press the composite paper tube 117 downward, the lowermost composite paper tube 117 pushes the blocking block 115 and the blocking rack 111 to move outward, the retraction spring 116 is stretched, the lowermost composite paper tube 117 falls onto the rotating roller 206, then the lower pressure electric cylinder 103 is retracted, the retraction spring 116 rebounds, and the composite paper tube 117 above the lowermost composite paper tube 117 is lifted up by the blocking block 115, so that there is only one composite paper tube 117 between the blocking block 115 and the rotating roller 206. The switching motor 106 rotates to drive the eccentric turntable 107 to rotate, thereby driving the eccentric connecting rod 108 to rotate, thereby driving the grinding cover 109 to rotate relative to the lower seat 104, and at the same time, the rotating rod 110 pushes the tube inlet rack 101 to slide along the horizontal slide rail 105, so that the tube inlet rack 101 leaves the top of the lower seat 104, and at the same time, the grinding cover 109 reaches the top of the lower seat 104, and the grinding sheet 113 contacts the composite paper tube 117 and presses the composite paper tube 117 downward, the downward pressure spring 114 is compressed a certain amount, and the pressure rod 112 slides along the grinding cover 109. The descent of the composite paper tube 117 will push the two rotating rollers 206 to slide outward along the lower seat 104 through the extending shaft 207. At this time, the grinding sheet 113 is in close contact with the composite paper tube 117 and has a certain pressure. The grinding motor 201 rotates to drive the motor gear 202 to rotate, and drives the transmission gear 204 and the long shaft 203 to rotate, and drives the transmission gear 204 and the long shaft 203 on the other side to rotate synchronously through the transmission belt 205, drives the lower gear 212 to rotate, drives the outer gear 214 to rotate through the lower transmission belt 213, drives the upper gear 215 to rotate through the outer transmission belt 216, and drives the rotating roller 206 to rotate through the upper transmission belt 217, thereby driving the composite paper tube 117 to rotate through the rotating roller 206, and grinding the outer surface of the composite paper tube 117 through the grinding sheet 113. When the grinding sheet 113 presses the composite paper tube 117, it pushes the rotating roller 206 and the pressing block 209 outward, and the pressing spring 210 is stretched, driving the upper rotating rod 211 and the lower rotating rod 208 to rotate, and the pressing spring 210 makes the rotating roller 206 close to the composite paper tube 117.When the rotating roller 206 and the extending shaft 207 slide outward along the lower seat 104, the short rotating rod 315 will be driven to rotate, thereby driving the connecting frame 301 to descend, and the lower spring 314 will be compressed, so as to adjust the position of the inner grinding head 303 according to the position of the composite paper tube 117. The lower output wheel 218 rotates and drives the upper inner wheel 312 and the upper outer wheel 311 to rotate through the lower side transmission belt 313, and drives the upper transmission wheel 307 and the gear column 305 to rotate through the inclined transmission belt 308, thereby driving the end gear 304 and the two-way screw rod 302 to rotate. Under the action of the inner convex ball 306, the two-way screw rod 302 and the inner grinding head 303 spirally move forward to grind the inner wall of the composite paper tube 117. Then the switching motor 106 rotates to drive the tube inlet frame 101 to slide and the grinding cover 109 to rotate. Before the tube inlet frame 101 reaches the top of the lower seat 104, the ground composite paper tube 117 is taken out.
